Wireless sensor networks are embedded networks that are highly restricted to energy, bandwidth and processing power. Even though wireless sensor networks operate with limited resources, sensor nodes are required to do more functions compared to nodes in other data networks. Sensor nodes work as both hosts for processing sensed data and routers for forwarding packets. To decrease such a workload in sensor nodes, the authors propose a multicasting method that minimizes the number of transmission and forwarding in each sensor node. The proposed multicasting algorithm is simulated in the TOSSIM simulator and implemented with Crossbow MICA2 microsensors.
